RAILWAY-WAGONt `COUPLING.

SPECIFICATION formingpart of Letters Patent N o. 723,265 `,dated March 24, 1903.

i Application filed November 19, 1902. Serial No. 131,961. (No model.)

To all whom/'it may concern:

Be it known that LCRL GEBERS, machin` ist, of 28 Friedrichstrasse, Wandsbeck, Kreis Wandsbeck, in the ,Province of Schleswig- Holstein, Kingdom of Prussia, Empire of Germany, haveinventednew and usefulImprovements Relating to Railway-Wagon Cou plin gs,

(for which patent applications are made in Germ any, dated May 28, 1902, and Great Britain, dated October 28, 1902,) of which the following is a specification.

This invention. relates `to improvements in railway-wagon couplings, and two Aconstructional forms of couplings in accordance with the invention are illustrated in the accompanying drawings.

The object of the invention is to provide an i automaticcoupling, which will further permit, when thecoupling has taken place, of

drawing the two wagons vclose together tol the same extent as has hitherto been usually done bymeansof the known form of spindle as is prescribed for express-trains. Uncou plin g is effected by hand without it being necessary, however, for the shunter to get between the wagons to be uncoupled.` Both the coupling and uncoupling may be effected from od the track.

Iu Figure 1 ofthe accompanying drawings a railway-wagon provided with my improved coupling device is illustrated in end elevation'.

the movement `ofthe coupling-hooks; Fig. 5

`shows the manner of their positive disengagel a crosssection onthe line G H of Fig. 7.

The coupling consists of aframe 1 and hook 2. The frame lis mounted at the end of the wagon 3 in such a manner as to be capable of oscillating around avertical pivot 4. The frame and its hook are normally maintained Fig. 2 shows the coupling in side ele-` vation. Fig. 3 represents the coupling-hooks of two wagons encounteringeach other im` l mediately prior to coupling. Fig. 4 illustrates in a position exactly at rightangles to the wagon end by means of an arm 5, sliding upon a curved bar 6, and maintained in place be tween two springs 7 and 8.

When it is desired to couple two wagons together, lthe hooks2 2 ofthe respective coupliugs encounter each other, or when the wagons are loaded to a different degree and the hooks slide past each other `the .hook of the one part willencounterthe verticalfront portion ot` the frame of `the other part, and the two couplings are pressed apart. The arm 5 `then presses against the spring 7, and owing to this spring the hooks yield, so that as soon as they have passed eachother they immediately resume their normal position and se- 'curely engage one with the other.

By means of one of the worm-wheels 1l, mounted upon the shaft 10 and actuated by lthe lever 9, the toothed wheel 12 is rotated.

The hub 13 of this wheel serves as a nut for a screw-spindle 14, upon the front extremity of which the coupling-frame 1 is iixed. By the rotation of this toothed wheel12 the whole frame is displaced after coupling has been edected in the direction of the wagon 3, so'

that the twowagons are drawn together un til the buffers lie as closely together as desired. f

When uncoupling is to be effected, the spindle 14 is advanced by means of the crank 9 and nut and wheel 12 13. The arm 5 then encountersresistance from the spring 8, and upon further displacing the spindle 14 the frame 1A is displaced laterally until it occupies the position indicated in dotted lines in Fig. 5,` whereupon the hook of this portion of the coupling is released from that of the other portion.

In order to permit of a certain amount of lateral play in the coupling in rounding curves, springs are provided upon either side of the arm 5.

If a curve, the center of which may be assumed to lie on the upper edge of the drawing, necessitates a movement of thel coupling members, the arm 5 will act upon the spring 7. If the curve is in the opposite direction, the action would be against the spr-ing 8.-

In Fig. 7 a couplng-hook 15 is shown, which merely consists of a laterally-formed hook capable of oscillating around a vertical pivot without a frame. This form of hook is also,

provided with the lateral arm 5,'which is adapted to act upon the springs7 and 8. For the purpose of advancing or drawing back the hook a continuous draw member is provided. With this object the draw-bar 16,

situated beneath the wagon 3,is formed with' described, because the sleeve 19, acting as a nut for the spindle 14, displaces this latter forward or backward, while the entire draw member is capable of displacement in the longitudinal direction as soon as there arises a difference between the tractive effort and the movement of the wagon. The prolongation 20 of the spindle 14 is of rect-angular cross-section and fits in a passage of similar cross-section in the thickened portion, while this thickened portion and its guide are also rectangular, thus securing the hook 15 in position. A striking' pin or stop 23, inserted in a slot 22, limits the movement of the spindle 14 in the longitudinal direction, while a spring 24 fits with its nose 25 into a recess 26 ot' a screw-thread on the spindle 14 as soon as the hook 15h-as attained its normal position-#that is to say, that position lin which it is capable of engagement with a hook occupying a like position.

the Wagons, which takes place in the running of a train.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a railway-wagon coupling, the combination of a laterally-yielding coupling-hook, a Vertical spindle upon which said hook is mounted, a threaded rod carrying said spindle, a tapped worm -wheel engaging said threaded rod, a worm engaging said wormwheel and means for manually turning said worm.

2. In a railway-wagon coupling, the combination of a coupling-hook, a vertical spindle on which said hook is pivoted, a lateral arm on said hook, springs engaging the extremity of said arm, means for moving said vertical spindle longitudinally of the wagon whereby the hook will be caused to swing on its pivot substantially as described.

3. In combination, a laterally yielding coupling-hook mounted on a threaded rod, a nut engaging said threaded rod, a continuous draw-bar having a flange engaging said nut, a worm-wheel engaging said nut and adapted to revolve it, a worin engaging said worm. wheel, means for turning said worm and means for preventing the rotation of the threaded rod, substantially as described.

In testimony whereof I affix my signature -in presence of two witnesses.
